BACKGROUND 1. Technical Field

The instant disclosure relates to a wireless charging mouse, and inparticular, to a wireless charging mouse having a coil board internallyembedded within a lower housing of the mouse.

2. Description of Related Art

In today's world of ever advancing technology, personal computers,laptops, tablets, and portable devices of different sizes have becomeirreplaceable tools in people's lives, and mouses are common inputdevices for the abovementioned equipment. Further, the wireless chargingmouse has gradually been adopted by people because of the convenience ofwireless charging. However, the existing design of the wireless chargingmouse places the coil board on the lower housing of the mouse in astacked manner, thus creating a stack height. This design not onlyoccupies the internal space of the mouse, but also causes the coil boardof the mouse to be easily damaged during assembly, thereby increasingthe defect rate during assembly of the mouse.

In this regard, the present disclosure provides a solution to overcomethe aforementioned drawbacks.

SUMMARY

The object of the present invention is to provide a wireless chargingmouse that can overcome the aforementioned drawbacks.

In order to achieve the object above, one of the embodiments of theinstant disclosure provides a wireless charging mouse including an upperhousing, a lower housing, and a coil board. The lower housing is fixedto the upper housing and has an aperture for exposing a displacementsensing module. The coil board is integrally embedded in the lowerhousing.

Preferably, the coil board is completely enclosed in the lower housing.

Preferably, the coil board is partially enclosed in the lower housing.

Preferably, the coil board is sized and shaped to correspond to thelower housing.

Preferably, the coil board has a plate board and a coil formed on theplate board.

Preferably, the plate board has an opening and a plurality ofpositioning portions extending from a periphery of the opening.

Preferably, the plate board is provided with a plurality of positioningnotches recessed from the periphery of the opening.

Preferably, the plate board is made of a polyimide material.

Preferably, the coil is an irregularly shaped coil.

For the wireless charging mouse provided by the embodiment of thepresent invention, the coil board is embedded in the lower housing ofthe mouse by means of injection molding. This eliminates the stackheight that the coil board may create at the lower housing of the mouse.This design not only does not occupy the internal space of the mouse,but also prevents the coil board of the mouse from being damaged,thereby reducing the defect rate during assembly of the mouse.

In order to further the understanding regarding the present invention,the following embodiments are provided along with illustrations tofacilitate the disclosure of the present invention.

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

The aforementioned illustrations and following detailed descriptions areexemplary for the purpose of further explaining the scope of the presentinvention. Other objectives and advantages related to the presentinvention will be illustrated in the subsequent descriptions andappended drawings.

Referring to FIG. 1 to FIG. 7, in one preferred embodiment of thepresent disclosure, the wireless charging mouse (hereinafter referred toas a mouse) includes an upper housing 1, a lower housing 2, and a coilboard 3. It is worth noting that the mouse provided by the presentinvention further includes other components such as a scroll wheel,buttons, and other elements for controlling the mouse, which are notfurther detailed herein. Hereinafter, the disclosure will focus ondescribing what is considered the features of the present invention.

In particular, the lower housing 2 is threadedly fixed to the upperhousing 1, and an accommodating space is formed between the upperhousing 1 and the lower housing 2 for accommodating the electroniccomponent, such as a displacement sensing module 4. The displacementsensing module 4 is used to determine the moving direction and themoving distance of the mouse, thereby completing the positioning of thecursor. The module may be an optical displacement sensing module or alaser displacement sensing module. The lower housing 2 has an aperture21 for exposing the displacement sensing module 4 described above.

The coil board 3 is integrally embedded in the lower housing 2.Specifically, the coil board 3 is integrally embedded in the lowerhousing 2 by means of injection molding, so that the coil board 3 andthe lower housing 2 are formed as a one-piece structure. In addition,the coil board 3 may be completely enclosed in the lower housing 2 ormay be partially enclosed in the lower housing 2. Moreover, the coilboard 3 is sized and shaped to correspond to the lower housing 2,namely, the coil board 3 has the coil 32 with an outer contourcorresponding to the lower housing 2, so that the magnetic inductioneffect can be enhanced without sacrificing the internal space of themouse.

Further, the coil board 3 has a plate board 31 and a coil 32 formed onthe plate board 31. The coil 32 may be a coil formed by etching on acopper-clad plate board 31. The plate board 31 may be a Rigid PCB or aFlexible PCB, and its material is preferably made of Polyimide (PI). Thematerial itself has high thermal stability, with good radiationresistance and heat resistance, and allows processing at temperatures ofup to 500° C. As a result, the coil board 3 has good heat resistance, sothat the molten plastic material can be directly distributed around thecoil board 3 during the injection molding process, and the one-piecestructure is formed after solidification.

Moreover, the plate board 31 of the coil board 3 has an opening 311 anda plurality of positioning portions 312 extending from the periphery ofthe opening 311. The positioning portions 312 can cooperate with thepositioning structure to position the plate board 31 in the mold cavity(not shown). After the lower housing 2 is molded in the mold cavity, thelower housing 2 can be integrally combined with the coil board 3. Theplate board 31 of the coil board 3 is also provided with a plurality ofpositioning notches 313 recessed from the periphery of the opening 311.These positioning notches 313 can be fitted with the positioningelements, such as positioning posts, to position the plate board 31 inthe lower housing 2 of the mouse.

In addition, the shape of the coil 32 may vary depending on particularimplementation. For example, coil 32 may be a circular, rectangular,square, or irregularly shaped coil. In this embodiment, the coil 32 isan irregularly shaped coil to correspond to the contour of the plateboard 31.

In summary, the present invention embeds the coil board in the lowerhousing of the mouse by means of injection molding, instead of placingthe coil board in a stacked manner at the lower housing of the mouse asis the conventional method. In this way, the present disclosure can atleast provide the following advantages: (1) more effective use of theinternal space of the mouse. (2) a stacking height of the coil board inthe lower housing of the mouse can be avoided, so that the mouse can bemade thinner and shorter. (3) the size of the coil board is adapted tothe size of the lower housing of the mouse, and the magnetic inductioneffect is enhanced. (4) the coil board is hidden in the lower housing ofthe mouse, so that the coil board is not easily damaged, therebyreducing the defect rate during assembly of the mouse.
